iBe it. knjown that I, GUsrAv HAnrnR, citizen 'of .the United States,residingat Chi- `Illinois, have invented certain newandusefulImprovements in Electric-Light Fix# tures,.fof which lthe-following .is aspecification. v f

:'Thisinventionrelate's to electric fixtures,

. and more particularly to Ithe .mountingvand manipulation-of the shadesand. globes and .the adjustment of the electric lampl support :withrespect to the other parts. The principal Lobject of the invention is aprovision of' an improved construction, combination .and arrangement bymeans of whichthe adjustment may be carried out.

In the accompanying drawings, "Figure -1 isaview partly in section and`partly broken away illustrating la construction which embodies thelprincipalv features of my invention; Fig. V2 is a sectional detail ofthe globe locking mechanism; Fig. 3 i's a side'elevation ofthe partshown in Fig. 2; Fig. 4 isa plan view of the socket-adjustingmechanisml.; Fig. 5 y'is a side velevationof-the socketadjustingmechanism; Fig.- 6 is a sectional .view taken on the kline A-A of Fig.1; Fig. 7 is Va .plan view of `a modified form of socket-,adjustingmechanism; Fig. 8 is a side elevation `of the same; Fig. 9 is a view:o'f the end of the socket-adjusting mechanism; Fig. -10 is ,a sectionalview vof a modified form of globe locking mechanism; Fig. 1 1 is adetail of the lock proper shown by Fig. 10; and Figs. 12 and 13 are planand elevation ,views respectively of thescreen protector clamping ring.Y Y .v

In order to .provide .an electric lamp fixturecertain provisions must bemade` for accommodating both the old form of electric lampswith carbonfilaments land also fthe newer nitrogen lamps, as well as for thedifferent sizes of lamps of `either kind. It is a welllknown fact thatlamps must be raised or `lowered with respect -to their shades, globes`and reflectors in' .order to produce 'the best lighting effects, andin-order to produce various lighting effects.

.In v*the npresent' exemplifcation of Emy invention a housing or holder5 is supported in any suitable manner, as for eXample,'by being threadedon the extremity of a pipe or conduit 6, and is preferably constructedof sheet or cast metal with a projecting flange 7 lat 'the top whichpartiallyzcovers lsocket downward.

Qn-wthe; inside lthisvhousing or holderis formed with., parallel ridges9V spaced apart to4 form `a guide-wayv forythe .slotted ex- Yytremities. -10 of a socket holder 11. )This l i threaded through ,a nutO13 whichsubstan-y tially fills the -guidefway and prevents the nutfrom' 'turning :so that the lsocket .holder may lbe readily heldin anyadjusted. posi-v tion in 'which it is placed; ,Y i,

, VThis socket holder 111s designed'and intended "to fsupport -zsocketsofl various sizes.

` In .thezsocket 14, shown by Figs. 1,4 and.5,

are recesses ,15 at the top'the'reof for the reception of a nut 16.'.Terminals 17 andlS are also provided at the; top of the socket forlconnection with theordinary Velectric conductors. The socket holder 11is formed j with ran upwardly extendingV yoke 19 vof sufficient width.tol allow. the socket, 14 to slidefreely therein the sides of thesocket being .formed with grooves 14a for the yoke so that it may beadjusted atcvarious heights with respect to the yoke.y Theupright sidesl of 'thejyoke are formed with slots20 (see Fig5) with an enlargement21' at .the bottom anda screw 22 iSv-inserted through the slot andthrough a suitable 'hole in thebody of thogsocket14 into the nut lateachside of .the socket. y.rllhese'screws 22 may beadyjusted to hold asocket at any desired height with respect tothe yoke, and the 'enlargedopening' 21 at thel bottom of the yoke enables .one-toremove the socketfromtheI yoke without 'removing the screws22 vfrom the socket, .by`simply loosening them and sliding the If it is l desired tosecureasmaller'sockety ,j to thesocket-holder 11y a pair .of socket 7clamping 'members 23,'as shown `in Figs. '7 and 8, may be employed.These members 23have bent extremities 24 which'engage over thesides ofthe yoke portion v19 .and are held together by means of fasteningdevices 25. A socket 26 is inserted between them and by adjustingA thefastening devices 25 this socket maybe adjusted and held zin anyposition with -respect'to the yoke, kthe members 23 being slidable withrespect 'tothe yoke and the socket 26 itself being slidable with respectto the `members 23.

.Atthe bottom of the holder 5 is a shade or .reflector ,27 which isl,preferably secured This shade preferably has anV upwardly eX- tendingportion 33 which extends within the holder' at the bottom, and theobject of the hinge above described is to prevent the I shade fromhitting van lelectric lamp 34, in-

serted in the socket when the shade is rvtated about its hinge 'for anypurpose. A globe 35 is usually inserted within the shade and invthe'present invention it is held in place by means of one or morei'ixedsupports 36 projecting from the inside of the n shade and by meansof a locking member 37 preferably pivoted at the same place as the latch32 of the shade latching device and extends through a suitable aperture38 of the shade (see Fig. This member 37 will remain in place as longasthe upward projecting portion e3 of the shade is within the holder 5. Assoon as this side of the shade is rotated downwardly so that the lockingmember 37 is freefro'm contact with the end of the holder 5 this member37 may be rotated outwardly about its pivot through the aperture 38 soAthat the globe 35 may be removed from the shade as desired. The lowerend of the globe 35 is preferably provided with an aperture 39 throughwhich air may enter, and through which dirt and the like will fall, theair escaping through the apertures 8 so that the circulation of air maybe providedaround the lamp.'

Tt is obvious that when lamps of'large size, as shown in Fig. 1, areused, there is danger of the shade and globe striking the lamp unlesssome means is provided to avoid it. This is the reason for employing thehinge structure shown. Upon referring to Fig. `1 it will be seen that itthe shade and globe are swung downwardly upon the hinge taking thedotted line 40 that edge of the shade` and globe opposite the hinge willstrike the lamp; but after the upward eX- tension 33 ofthe shade isfreed from the bottom of the holder 5 the link 30 of the hinge permitsthe shade and globe to swing laterally so that the opposite edge takesthe path indicated Aby the dotted line 41, whereupon the continueddownward movement of the shade and globe about the hinge will describethe curved line thereby clearing the lamp 34 without removing orinterfering with it in any way. A protectl ing'screen 43, preferablj7 ofreticulated material, may be secured to the periphery of the shade 27 bymeans of a clamping ring 44. This clamping ring is preferablychannel-shape in construction embracing the edves or beads both of theshade and of the screen with an adjustable locking device, as shown moreclearly in Figs. 12 and 13, for holding it in place. This catchcomprises abent member 45 secured to one end of the ring 44 withperforations 46 inits opposite sides. 'A pin 47 is inserted through thealined p'erforations and through eyes 48 of a latch member 49. Thislatch` member 49 cooperates with a fixed catch 50 on the other extremityof the ring from which'also projects a tongue 51 adaptedto be insertedin the member 45 beneath thelatch 49. The

seif'eral perforations 4G kprovide the adjustment necessary forkclamping the rings in position. n f

-. It is also contemplated that the globe (Fig.

5) may be connected directly to the shade y or to the holder by means ofa separate fasteningldevice, as shown by Figs. l() and 11.

In this case the holder 5 has secured to it one orv more Xed brackets 52or adjustable screws 53 and is formed-on one side with a f perforation54 through theholder with lugs 55 at the side thereof on the outside. Alever 56 is pivoted in the lugs 55 and has an arm 57 adapted to beengaged by a catch 58 pivotally mounted on ascrew 59. In order to insertorr remove the globe 35 the catch 58 is rotated as shown in dottedoutline in Fig. 11, thearm v57 is depressed whereuponfthe globe 35 maybev inserted or removed, and if inserted the lever rotated to s Toprevent unauthorized removal of the clamping ring 44 and the droppingiofthe shade 27, seals 60 are provided, such forexample as a wire loop withits ends leaded together. A wire is inserted through the catch 50 afterthe. latch Vmemberis pressed over it to lock thev ring 44, and anotherwire is inserted through catch 3l in a similar manner, it beingnecessary to break the wire or seal to open the ring or shade.

At the bottom of the globe 35 is a screen G1 larger than the aperture39, simply laid therein and held by its own weight.- This screen is `toprevent the entrance of bugs and insects which gather' about a light oi'this kind, clogging and dirtying the globe unless some means is providedto exclude them.
